In addition, a similar exit screen appears when you exit most other screens, and it can be used to save settings. Performing Configuration Tasks NOTICE: You will lose any data on your hard drives when you create a RAID configuration using the following procedures. Back up data that you want to keep before continuing. NOTE: Your RAID array cannot exceed 2 Terabytes in size. Any space beyond the 2Terabyte limitation will not be usable. The two options for creating a new RAID volume are Create IM Volume and Create IS Volume. IM stands for integrated mirroring. IS stands for integrated striping. Additional information is available on the configuration screen. Creating a RAID Level 0 Configuration NOTE: RAID 0 does not provide any data protection in the event of hard drive failure. It is primarily used to increase performance. NOTE: Once the number of hard drives in a RAID volume (virtual disk) is set, it cannot be changed. Follow these steps to create a RAID 0 volume on a SAS 6/iR controller that does not currently have a RAID volume configured. 1 Select a controller from the Adapter List in the Configuration Utility. 2 Select the RAID Properties option. 3 Select Create IS Volume when you are prompted to create either an IS (striped) RAID volume or an IM (mirrored) RAID volume. The next screen shows a list of hard drives that can be added to a RAID volume. 4 Move the cursor to the RAID Disk column. To add a hard drive to the RAID volume, change "No" to "Yes" by pressing the , , or space bar. As hard drives are added, the Virtual Disk Size field changes to reflect the new size of the RAID volume. Advanced Features 45
